My car alarm was going off at random times sometimes in the middle of the night so i disconnected the battery one night. then the next morning when i connected it again and started the car up the radio would not work. I called acura and got the code entered it and it still would not work. I got this faint beeping sound. the sound happened with other random codes i entered. Also today I tried to unhook the batter again and start fresh and punch in the code. Still didn't work. Is there a special way to punch in a code? Does anyone have any ideas or know what could be the problem? All suggestions welcome!
